What should I do if my condensate pipe freezes in cold weather?

Locate the blockage and thaw the frozen pipe by applying a hot water bottle, a microwaveable heating pack, or a cloth soaked in hot water to the exterior of the pipe near the blockage. Do not use boiling water as this can damage plastic pipes. After thawing, reset the appliance and wait two or three minutes for it to restart, and if it does not restart call Worcester, Bosch Group on 0330 123 9339. (Page 14)
